Recent changes for virtual machine support and the new powerd utility have been rolled into the release branch for DragonFly. They’ll probably be in the next point release, or you can rebuild a release machine now for immediate access.

Also mentioned in the update from Matthew Dillon, DragonFly-master users should upgrade carefully as DragonFly migrates to using LibreSSL in base, and dports-based LibreSSL in dports.

DragonFly-master (i.e. 4.7) now disables DSA keys by default. If you are using a DSA key for SSH/SFTP/whatever, you should change it anyway. Otherwise, it won’t work without workarounds after your next 4.7 upgrade, or by the time of the next DragonFly release.

You probably didn’t use this anyway

The last bits of Linux emulation have been removed from DragonFly. It’s 32-bit, so it’s been unsupported since DragonFly went to 64-bit only with the 4.0 release. Also, some other 32-bit only items are gone, including the cs, ep, ex, fe, and vx network drivers. It’s almost impossible that anyone was using it, but it’s notable because that’s some… 15-20k lines of code gone? Removal of unused code is also positive.

OpenSSH, OpenSSL updates

Because this always happens just after I create a DragonFly release, there’s a new version of OpenSSL. However, this is for version 1.0.2. 1.0.1 is what’s in the release, and it’s supported through the end of the year.

OpenSSH has a major version bump in DragonFly, to 7.3p1. This means some features – specifically patches for High Performance Networking – are no longer there, and you’ll get an error if your config file requires them. Either remove the options from your config, or install OpenSSH from dports.

HEADS UP: world needs rebuilding

I’m a bit late on this, but: If you are using DragonFly-current, you will need to rebuild world. If you are on 4.4, this won’t matter until you go to 4.6, and you’d be rebuilding world and kernel for that anyway.

(4.6 will probably be tagged this weekend.)

DragonFly 4.6 release candidate 2 available

DragonFly 4.6 release candidate 2 has been tagged. You can pull it directly from the master site in img or iso form (check your local mirror instead if possible), or shift to the new tag.

“Where is RC1?” you may ask? I tagged the first release candidate some days ago, and this bug was immediately found right after. It was easier to go right to RC2 once a fix was found.

This candidate will probably lead directly to a release version, so if you want to run the release version exactly, wait a few days.

In Other BSDs for 2016/07/23

Adding a new “BUG” category, cause there’s enough ongoing BSD user group activity these days that it’s a reoccurring theme. That makes me happy.

NVMe and IOPS

Matthew Dillon added NVMe support recently, and he also made some changes to DragonFly’s I/O system. His test system was able to reach over a million IOPS. That’s bananas!

BSD Now 151: Fuzzy Auditing

Fuzzing sounds cute, but it’s about finding security problems, not checking for adorable guinea pigs or llamas or something like that. It’s also episode 151 of BSDNow. It looks like there’s no specific interview this week, but plenty of interesting topics and links listed.

i915 update to 4.4

the i915 support in DragonFly now matches the Linux 4.4 kernel, which is good news if you have a Broxton, Skylake, or Cherryview processor, plus it adds a variety of fixes.

Looking at your battery

If you want to check battery life, ‘sysctl hw.acpi.battery.life’ may help, as Sepherosa Ziehau points out. I’ve always used ‘acpiconf -i 0‘, myself.

UEFI install story

I like finding “This is how I did it” stories from people, as they are often really useful for anyone else trying to do the same “it”. Here’s Dave MacFarlane’s UEFI install story. (Note he’s still needing touchpad support.)

Reminder: move your Hammer cleanup

A useful tip: if your DragonFly machine isn’t usually on 24/7 (e.g. a laptop, not a server), you should move your Hammer cleanup from 3 AM to sometime when the computer is normally on.

UEFI booting and manual installation

Two tips for video and audio

That’s one tip per subject, really. If you need to set up a ‘video’ group for xorg, here’s the one-liner to do so. If PulseAudio annoys you, which is not uncommon, ‘chmod -x /usr/local/bin/pulseaudio’ and it’ll go away.

ipfw3: lockless in-kernel NAT

It’s exactly what the title is: ipfw3 now does NAT in-kernel, without locking. I have no benchmarks to point at, unfortunately. The commit has usage examples.
